[Desire Q&A, Help & Troubleshooting] knyazs:
Hello everyone,

I bought HTC Desire few weeks ago - phone is fantastic but I have an issue: GPS signal is loosing in the city! On the open road everything work fine, GPS is very accurate and has fast response but in town... it's another story. As soon as I came between higher (10 stories) buildings my phone looses GPS signal.

What can be done? Is there any way to hack software so phone could use signals under 20%?

Thank you in advance,

Miljan
[Desire Q&A, Help & Troubleshooting] MasDroid:
You could root the Desire and then try flashing a different radio version to improve GPS signal strength.

In the meantime, you can try the following:

1. Before you turn on the GPS, change to Airplane mode.

2. Start the GPS.

3. Start your nav app and let it get a signal.

4. Turn off Airplane mode.
[Desire Q&A, Help & Troubleshooting] knyazs:
Hey MasDroid,

thank you for this really fast reply! :)

I'll definitely try second method you suggested but either I'm software developer, I've never been in touch with android since now so I really don't know what is "different radio version"!? Can you point me to some site or forum where I can read about it?

Best regards,

Miljan
[Desire Q&A, Help & Troubleshooting] MasDroid:
Here is a link which explains the rooting procedure in more detail:

Radio rom - The radio software sits between windows mobile and the hardware. It controls the hardware based on what you want to do. There are all kinds of reports of better/worse battery life, connection strength (including GPS and Wi-Fi), sound quality reception when flashing different to radio versions. You can find out your stock radio rom version on your phone by going to Settings > Abount Phone > Software Information. Check the baseband version - this is your current radio version.

Some roms (like the new Froyo with Sense UI) require specific radios (32.41.00.32U_5.08.00.04 or 32.42.00.32U_5.09.00.08), read the rom posts in the Desire Development section of the forum (http://ip208-100-42-21.static.xda-developers.com/forumdisplay.php?f=628) for more info

A list or available radio's are available here:

http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=687464

The roms that start with 4.x are generally based for Eclair 2.1 custom and generic roms, the ones that start with 5.x are for Froyo 2.2 roms.

Be careful is you are sim-locked (network-locked) to Orange - the newer Radio verions will network lock your phone after flashing (unless you flash back to stock Radio version or buy a network unlock code). There are reports that the newest Froyo Radio rom (32.42.00.32U_5.09.00.08) does work on Orange even if sim-locked to their network.

Hope that helps you out!
[Desire Q&A, Help & Troubleshooting] knyazs:
Hey, thanks for this useful tips...

If I figure it out correctly, first I need to root (whatever this means and it's reversible) my phone and after that I can load Radio and Froyo... done in 4 hours :) I'm kiddin'

Procedure looks very complicated but with video it becames easy. My question is: can I restore factory defaults after any of these procedure(s)?

Thanks again!
[Desire Q&A, Help & Troubleshooting] MasDroid:
Root gives you super user access to your phone, just a way to unlock it in order to flash roms and make further changes.

You create a Gold Card if your phone is branded first, then root, and flash a custom rom and radio, if necessary.

Yes, by flashing a rom, you are changing the device firmware. When you perform a hard reset/factory reset, your phone will resort back to factory settings of your current installed rom.

If you ever want to unroot your phone and to return to stock rom and radio, just flash the relevant RUU file.
[Desire Q&A, Help & Troubleshooting] knyazs:
Nice explanation this time, I figure it out :)

How can you see if phone is branded? Is there any app or it can be seen somewhere else?

Thanks again mate, you are really helping me with this tips.

Bye
[Desire Q&A, Help & Troubleshooting] MasDroid:
Yes, again, Go to Settings > About Phone > Software version. Check what the firmware version is - branded is x.xx.161.x, unbranded is x.xx.405.x.

You can also tell if your phone is branded by looking for any network carrier logos on bootup (i.e. Vodafone, Orange, T-Mobile, etc) and pre-installed apps that have network branding.

If there is none and your firmware version is x.xx.405.x, then you will not need to create a Gold Card to bypass CID checks.
[Desire Q&A, Help & Troubleshooting] knyazs:
Thanks again MasDroid,

my firmware version is 405 (unbranded)

Bye

Ok, take care... ciao! :D

Don't all GPS lose signal when surrounded by high buildings? They rely on triangulation from satelites and if they can't see the sky ... well. My Tom Tom was terrible in London ....
[Desire Q&A, Help & Troubleshooting] MasDroid:
Good point... i would imagine this would be the main cause to the OP's problem.

Hi all,

i have published some thoughts regarding HTC Desire and the new HTC Sense version on my Blog.

Hope this is helpful for anybody thinking about getting an HTC Desire:

Let me know if you have any questions. In the end i opted for the Nexus One and i'm currently working on my FroYo review. But the HTC Desire is still one of the best Android devices IMHO.

I followed the advice from this post on Android Forums and am getting amazing battery life. If this has been posted elsewhere on XDA, please forgive me.

http://androidforums.com/tips-tricks-evo-4g/125602-htc-evo-battery-life-guide-41hours.html

I am on track to hit 50 hours on one battery charge. I am currently using the stock 1500mah battery. I will report back tonight or tomorrow with the final total.

I am using the paid version of SetCPU and have actually set slightly more aggressive power control profiles. (see below). I am not using live wallpapers. I only use radio control widgets and the HTC calendar widgets. I am running DC 3.2.3 with the latest radio and wimax drivers. I use Advanced Task Killer in Aggressive mode set to kill every 30 minutes. I use Timeriffic to turn on/off WiFi and 3G depending on whether I am at home or away. I use DConfig to ban Sprint Nascar, Twitter and Friendstream. I have brightness set to about 15% with a 2 minutes screen timeout.

These are my SetCPU Profiles. I have no noticeable performance degradation.

on a stock battery? i call bull!
[EVO 4G General] davidboyd:
No sweat off my back if you are skeptical. Why not try it yourself and see rather than call someone a liar.
[EVO 4G General] acrh2:
You should be able to hit around 100 standby hours, not 50.

And without setcpu.

In fact, setcpu profiles is probably what's making your phone drain twice as much energy as it should.
[EVO 4G General] tonyh703:
my battery

battery after 25+ hrs not charging, using 4G for about an hour, d/l'ing apps, texting, calling, showing off, etc.
[EVO 4G General] davidboyd:
I am not talking about taking the phone off charge and letting it sit in stand-by. I am checking Gmail, moderate web surfing, checking Exchange email, phone calls, texting, about 20 minutes of Google Navigation, etc. I have purposely stayed away from games and movies. After this charge drains, I will add those into the equation.
[EVO 4G General] markus_del_marko:
what kernel are you using? because with heavy usage and everything mostly disabled on my evo...running the new damage rom i get maybe 12 hours max.
[EVO 4G General] davidboyd:
Firmware - 2.1-update1

Baseband - 2.05.00.06.10

Kernel - 2.6.29-789bf291 htc-kernel@and18-2 #1

Build - DamageControl v3.2.3

Software - 1.47.651.1

PRI - 1.34_003

[EVO 4G General] markus_del_marko:
i must have a defective battery then because that's what im running too.
[EVO 4G General] davidboyd:
Have you config'd the same SetCPU power profiles and tried what I said I was running? I have edited the original post to provide more details about my setup. Take a look and give it a try.

I have also purchased the $9.98 charger with two batteries from eBay. I plan to run them through the same test later this week.
[EVO 4G General] J2the4son:
I am not impressed. I am running stock with no modifications and at the time of writing this I am at 26 hours with 20% left. I have auto sync off screen at 20%. Otherwise I have everything else normal.
[EVO 4G General] davidboyd:
Not trying to impress anyone. Just letting people know what is working for me. For the record, you are on track for 32.5 hours. While that is MUCH better than what a lot of people get from their EVO, it is still only 65% of what I am on track to hit today. To each his own.
[EVO 4G General] tonyh703:
Yea man I appreciate it, even though I already have my tricks to get mine up. I am at 16% with 28 hours unplugged. The only reason its so low is because I was driving around tryin to get some 4G yesterday, so that drained it about 10%. I am happy with the battery life now because I used to not make it through a 10-12 hr day w/o recharging.
[EVO 4G General] davidboyd:
26 hours, 45 minutes with 47% remaining...
[EVO 4G General] Shinzul:
I don't get how people are getting such huge numbers... I currently am running OMJ's 1.5 ROM with Netarchy/toast's kernel for the FPS fix.

I am running the paid version of SetCPU with all the same battery profiles set up. I only get about 12 hours of usage before I'm out... this would be moderate usage - couple of calls, light web browsing, texting, etc.
[EVO 4G General] tonyh703:
I made it 32 hours. I am running a live wallpaper though and I was strugglin tryn to find 4G connections yesterday.
[EVO 4G General] brownhornet:
Would love to see some unplugged screenshots
[EVO 4G General] davidboyd:
Tell me how to take screenshots and I will snap one later tonight.

I am not sure if this has helped, but I also did the battery trick that the Sprint or HTC rep suggested elsewhere on here. Charge to light turns green, power off and charge for an hour.... This did seem to help a bit before trying these new SetCPU settings.

Again, send me the steps for screenshots and I would gladly post them up tonight.
[EVO 4G General] tonyh703:
check the first page of this thread... i have a screenshot of 25 hours with 23% left
[EVO 4G General] tonyh703:
as long as you have root access, just go in the market and type screenshot. I have ShootMe.
[EVO 4G General] pongoface:
Tony what kernel are u using? I don't think I can get those results with near''s 3.7.1
[EVO 4G General] ronnienyc:
!

So you guys are slowing down the processor to extend battery?

How is the performance? (I was doing the same with the hero, but the peak speed was Overclocking, not underclocking ;-))

I have not been able to root the Evo for the life of me!
[EVO 4G General] davidboyd:
I did notice a slight performance hit when I fell below 50%. ONce the stock Messages program froze for about 10 seconds, displayed the Force Close/Wait dialog. I clicked Wait and it took off again. Other than that, I haven't really seen any performance degradation to speak of.

I was afraid that throttling the processor down to 245 when the screen is off would cause it to be really slow to wake up when calls come in, but I have not had a problem. I have received several calls and have not missed a one.

One thing that is also helping is using Timeriffic to shut off radios that I don't need based on a schedule. It is like Locale, but does not use GPS based location; only time profiles.
[EVO 4G General] davidboyd:
I just added screenshots to the first post.
[EVO 4G General] Casshern:
Testing this out. I will report my findings in about a 48 hour period. For my particular test, I split the charging into AC and USB differences. Overclocking on AC charging, maintaining 998* on USB charging.
[EVO 4G General] pongoface:
Read my signature, I have mad speed and when my phone sleeps it is at 245mhz. Phone to me runs flawlessly. Kinda like speed speeding on Intel chips. Lowers the power when u are relaxing and the speed u need it. Very happy with the performance ratio / battery usage. My evo is a totally different phone than it was stock. A prius gone Corvette.
[EVO 4G General] patelkedar91:
I'm not surprised.

I got 44+ hours with light texting and a little bit of browsing.
[EVO 4G General] th3_g00b:
yeah, just yesterday i hit 42 hours with like 25% batter left. that was with light usage. 25-30 hours with moderate and heavy is about 15-18 hours. the only profile i have enabled is when my screen is asleep its running at 245/245 and my main OC is 1152/128 (performance) :D

[EVO 4G General] DSwarP:
To those of you getting incredible battery times, what is your service like?

I think part of the problem is that the people getting great battery life are in areas where they are always in strong service.

And for the rest of us, our battery is terrible cause our service is so poor.

Am I right? Or are you superlong unpluggeders in areas with meh coverage too?
[EVO 4G General] pongoface:
I have froyo jit installed on top of fresh on this phone. My mflops are 10 with the processor throttled down to 537 mhz. I am faster than stock with half the energy.
[EVO 4G General] davidboyd:
I am getting ready to hit road pretty soon so I had to put the phone on the charger before I finished my "test". I was at 44 hours and 18 minutes with 17% still remaining. (screenshot attached) As you can see from the posts of myself and others in this thread, it is entirely possible to get 2 days+ from your phone without sacrificing performance or functionality.
[EVO 4G General] Cicatrize:
Not sure why you guys don't believe this. I'm running stock battery with Fresh Evo 1.0.1 with live wallpaper and used my phone fairly heavily yesterday and I was at 50% after 17 hours off charger. Seems the new ROMs coming out (maybe it's something HTC did in the most recent update) are really nice with the battery.
[EVO 4G General] tonyh703:
I have not flashed a custom kernal,

2.6.23-789bf291
[EVO 4G General] pongoface:
I believe you totally because I was on the stock rom and got 38 hours with moderate usage. All I am saying is that my phone is faster @ 537mhz(10mflops compared to stock 6 maybe 7 mflops @ 998 mhz and about twice the battery life. Also Phone usage is just a random description. Surfing and watching videos take more battery life than texting and talking on the phone.
[EVO 4G General] Cicatrize:
Well, I can't speak for the OP, but my usage yesterday was about 30 mins web surfing, 1 phone call, about 10 texts, and around 1-2 hours of 2D games.
[EVO 4G General] JaiCameron:
Hey Tony you mind sharing how you obtained that battery life I'd like to test your method.
[EVO 4G General] IOInterrupt:
It is definitely easy to get a long battery life out of the EVO utilizing JuiceDefender and SetCPU. I myself can get over 48 hours with those two apps with general "phone usage" (texting, calls, light surfing). I see some indicate they get even decent times with heavy use, but obviously their heavy use it different than mine.

My heavy use is considered CPU usage maxed 100%. In those cases, I think I can get a few hours out of my EVO =).
[EVO 4G General] tonyh703:
I have used this battery charging tip:

charge phone until light is green

take off the charger for a few minutes

turn phone off

charge phone for about 30 -60 minutes

turn phone on and wait a couple minutes

charge phone for another 20 minutes or so

I am not totally convinced that this is the only thing that is helping so this is what else I have done:

Removed apps such as:

DCUpdater

SprintTV

SprintNascar

SprintVVM

Twitter

Friendstream

Flickr

WifiRouter

I also went to settings > wireless and networks > mobile networks > unchecked data roaming, and unchecked enable always on mobile data (i have yet to suffer 3G performance degredation)

I have battery saver mode on in DCconfig

I have the power bar widget and sometimes I turn off brightness

AutoKill apps not on the ignore list after 1 minute
[EVO 4G General] tonyh703:
BTW I am at 57% going on 19 hours right now.
[EVO 4G Q&A, Help & Troubleshooting] chicubs:
Ok, here is my issue.

Both my google and HTC calendar on my Evo show my facebook contacts' birthdays. Wonderful.

However, when I look at google calendar on my laptop, the facebook contacts' birthdays are nowhere in site.

I can add events from my Evo's HTC and google calendar's and have them show up on my laptop's google calendar so it is not a fundamental syncing issue it appears.

Furthermore, when I subscribe to a calendar on my laptop's google calendar (lets say the chicago cubs), the Cubs schedule does not appear on my Evo.

Anyone got any clues to these issues with Google Calendar syncing with the Evo's calendars?

...And yes I have searched and found nothing suitable for my problem.

Thanks so much for reading this.
[EVO 4G Q&A, Help & Troubleshooting] ju5tiiv:
As far as I know the Facebook calendar should be independent of the Google sync, I think of it as an overlay of such if that makes sense. With the Cubs calendar are you selecting it on your phone? Ie with your calendar open push menu -> more -> calendars and make sure its checked there? I have personally had to remove calendars and go back and re add them to get them to show up when they are new, hope this helps you out.

sent from my EVO from the dark side
[EVO 4G Q&A, Help & Troubleshooting] chicubs:
Ok, that make sense (pun not intended) that the facebook calender + sense is an overlay. Wish there was a way around it. For consistency's sake, I would like my phone's calendar to be the same as google calendar's on my laptop.

With the Cubs Calendar, I was adding their schedule through my laptop's google calendars (do not think there is way to do this via the Evo directly...Google Calendar > settings > calendar settings > calendars > browse interesting calendars > subscribe

Via this method, my Evo's calendar would not update with the google calendar which includes the Cubs schedule.
[EVO 4G Q&A, Help & Troubleshooting] ju5tiiv:
Okay so I tried exactly what you did and I did not get it to work either :(

Here is a solution I found from androidforums

Goto MySportsCal.com and download the schedule and import into a new calendar, then sync and voila. Worked flawlessly on my phone using this method!
[EVO 4G Q&A, Help & Troubleshooting] Bp3dots:
For the record, not all of the Google calendars you can choose on a PC are able to show on a mobile device. It says it somwhere on google, but it was hard to find when I was looking. (Had the same probelm trying to get the buckeyes' schedule lol)

And yes, Sense is putting facebook in, which is why you cant see it on a PC.
[EVO 4G Q&A, Help & Troubleshooting] chicubs:
ju5tiiv and Bp3dots,

Thanks guys. I actually found the answer a few minutes after you posted that. funny coincidence....anyway worked for me too.

So I guess have both my questions solved. Good stuff guys, thanks.

[Windows Mobile] leadpoizon:
Can't really figure out why this is happening. It doesn't happen with the Sprint 21889 SYS and XIP, but with all others. To clarify: When I plug in my headphones, and soft reset the phone, the phone boots with no sound. Everything else works fine. Anyone know why this could be happening? Thanks.
[Droid X General] Densefire:
So my brand new Droid X's screen was stuck off. No matter what button I pressed or combination of buttons I couldn't turn the screen on. The battery was at nearly full charge.

Not to mention the camera shudder got stuck on the 1st day of use... so I do have a replacement coming (that I had to pay for!)

So does anyone here know anything that could help me get my phone back until the replacement arrives? Maybe instructions on how to get into recovery mode?

Thanks in advance!

EDIT: I believe it may be the battery. I wont know for sure until I can get the phone to a charger. Sad though. Theres NO exception for a battery that lasts 20 MINUTES. I actually hope its not the battery...
[Droid X General] Nefariouss:
Have you tried pulling the battery?
[Droid X General] Densefire:
Yes, and when I put the battery back and try to turn on I noticed one of the lights at the top left of the phone will weakly flash and get weaker after every use of the power button. The phone is still not turning on.
[Droid X General] cbaty08:
Just take it back....
[Droid X General] Densefire:
I can't just "take it back" I HAD to pay for a replacement that should be here in a few days. =\
[Droid X General] cbaty08:
Why did you pay a dime????

I guess I must have missed something, but it doesn't sound to be your fault. I sure wouldn't have paid for a replacement due to a lemon sale......
[Droid X General] Densefire:
Sorry if I made the wrong impression lol but I called Verizon and they said no stores will have replacements for a while and I need a phone. So they directed me to Motorola and I paid a fee for a new one being shipped.
[Droid X General] ses1er:
I'm sorry if this sounds elementary but did you try to hold the power button to turn it on? I notice when the phone is off and I tap the power button, there's a weak light on the on left of the ear piece. Holding the button turns my phone on.
[Droid X General] rolandroland:
Yeah, my phone does the same crap when it drains to 0. After plugging it in I have to hold it, and even then sometimes I need to let it charge for 3 or 4 minutes before it'll turn on. Otherwise I just get that charge indicator screen that appears and disappears. Very annoying.
[General Questions and Answers] bndevelop:
I bought this phone too, and its true the hardware is good, even the g-sensor works... but the software.....

I have an 5y old htc P3600 with wm6.5 and it works really great even the battery...and the usability is light years ahead...

I bought this phone for its really fair price 80$, 68€ directly from china and for the double sim permissibility that is really great for me.

I notice that this question has a few months and no answers.. did you manage to change the OS? anything like android bada or wm working?

Hope you got it because I really like the phone but I prefer it with a better OS
